RooKEn' ATTACHMENT.

Application filed August 18, 1924. Serial No. 732,855.

To all whom it may concern:

Be it known that I, HILMAR MIOI-IAELSON, a citizen of the United States,residing at 722 Mott Ave, Vaukegan, in the county of Lake and State ofIllinois, have invented new and useful Improvements in RockerAttachments, of which the following is a specification.

This invention relates to new and useful improvements in rockerattachments for chairs and more particularly to rocker attachments whichare especially adapted for attachment to ordinary straight-leg chairssuch as diningroom chairs and the like.

The main object of my invention is the provision of a rocker attachmentfor straight-leg chairs whereby a diningroom chair or similar article offurniture may be readily converted into a comfortable rocking chair.

Another object of my invention is the provision of a rocker attachmentwhich can be quickly and readily attached to the lower ends of the legsof straight-leg chairs or readily detached therefrom whereby diningroomchairs or the like may be advantageously used for different purposes.

With the above and other objects in view, the invention consists in thenovel features of construction, the combination and arrangement of partshereinafter more fully set forth, pointed. out in the claims and shownin the accompanying drawings, in which: 7

Fig. 1 is a perspective view of a detachable rocker constructed inaccordance with my invention,

Fig. 2 is a side elevation showing the same applied to the legs of achair,

Fig. 3 is a detail longitudinal section of end of rocker showing thesame attached to the leg of a chair,

Fig. 4 is a detail section on the line 1- 1 of Fig. 2 and Fig. 5 is adetail section on the line 5-5 of Fig. 3. V

In carrying out my invention, I provide the rocker members which in thepresent instance include a body member 1 which is curved in proportionfor ordinary use and in the present instance the rockers are illustratedas preferably of aflat type. The for ward end of each of the rockers isprovided with a recess and attached to the body the rocker in alignmentwith this recess is a plate 3 which is detachably secured to the rockermember by means of screws 4 although various types of fastening meansmay be used.

The outer end of the plate 3 is notched as at 5. said notch beingarranged directly above the recess 2 and forms spaced arms 6 at eachside of the recess. The front legs 7 of the chair'are provided withdetachable buttons 8 which are held in place by means of screws 9, thusretaining the buttons 8 in position against the lower end of the legs 7.

The buttons 8 as illustrated are provided with an annular groove 10adapted to receive the spaced arms 6 of the plate 3 and it will be notedthat by forming the recess 2 in the forward end of the rocker, thebuttons 8 may be readily engaged with the arms 6 of the plate.

The body of the rocker 1 is longitudinally grooved as at 11 at a pointadjacent the central portion of the rocker and attached to the rear legs12 of the chair are the U-shaped clips 13 having pointed ends 1 1 whichare driven into the lower ends of the legs 12 and the arcuate bodyportion of the clips will be disposed within the groove 11 in the rockerfor not only retaining the legs 12 against transverse movement withrespect to the rockers but also limiting the longitudinal movement ofthe legs upon the rocker so as to retain the buttons 8 into engagementwith the arms 6 of the plate 3.

From this it will be apparent that the rocker members 1 may be readilyand quickly attached to the lower ends of the straight legs of a chairfor converting an ordinary straight-leg chair into a rocking chair.These rockers may also be quickly and readily removed from the chairwhen it is desired to use the same as a dining room chair or the like.

From the foregoing description taken in connection with the accompanyingdrawings, it will be apparent that I have provided an extremely simple,useful and inexpensive device for readily converting straight-leg chairsinto rocking chairs and the device may be quickly and readily attachedor detached as desired.

While I have shown and described the preferred embodiment of myinvention, it will be understood that various changes and alterationsmay be made without de 'iarting from the spirit of the invention or thescope of the appended claim.

Having thus described my invention, what I claim is:

In combination with the legs of a chair, buttons carried by one of saidlegs having an annular groove, U-shaped clips attached to the lower endof the other leg, of a rocker, recesses in its forward end and alongitudinal groove intermediate its ends, a plate at.- tached to therocker and projecting over said recess, a notch formed in one end of theplate providing spaced arms above said recess and adapted to be fittedinto the annular groove of the button, said U-shaped clips fitting intothe longitudinal groove for retaining the rocker against movementrelative to the legs. In testimony whereof I afiix my signature.
